Christensen Arms MPR 308 Win 20″ Carbon Fiber Barrel
Pros & cons
What works
- Weighs 6.90 lbs — over 2.5 lbs lighter than a comparable steel-barreled precision rifle.
- 20" carbon-wrapped barrel retains velocity better than a 16" barrel but is 40% lighter than a steel equivalent.
- Folding stock reduces overall length to 37.5" for transport, without tools.
- Sub-MOA accuracy guarantee with match ammunition removes performance guesswork.
Trade-offs
- Premium pricing at $2199.99 — the carbon fiber barrel technology commands a significant cost increase.
- No optic mount included — adds a minimum of $75-$300 for a quality mounting solution.
- The bare aluminum chassis can be cold to the touch in winter conditions without gloves.
- The loud, effective muzzle brake increases perceived recoil for nearby shooters on a line.

About this product
What is the Christensen Arms MPR .308 Win 20" Carbon Fiber Barrel rifle? It's a modular precision rifle (MPR) chassis system designed for shooters who require extreme weight reduction without sacrificing terminal ballistics or regulatory compliance for certain legal configurations. The core is its match-grade, 20-inch carbon-fiber-wrapped stainless steel barrel, which directly addresses the common trade-off between barrel length, weight, and velocity retention in the .308 Winchester cartridge. This setup is engineered for the shooter who needs to move fast over terrain but still demands first-round-hit capability at extended ranges.
What is the Christensen Arms MPR .308 Win 20" Carbon Fiber Barrel used for?
This rifle is for precision shooting applications where every ounce matters, specifically PRS-style competition stages requiring positional shooting and hunters pursuing game in mountainous terrain. The 20-inch barrel in .308 Winchester provides an optimal balance, maintaining effective velocity out to approximately 800 yards while shaving critical weight compared to a 24-inch or 26-inch steel barrel. Its folding stock and 6.90 lb bare weight make it exceptionally packable for backcountry hunts where a 10-mile hike in is standard.
How does the Christensen Arms MPR compare to the Stevens 334 Rifle in .308 Win?
The Christensen MPR is a purpose-built precision chassis system, while the Stevens 334 Rifle is a traditional budget-conscious hunting rifle. The MPR's carbon fiber barrel and aluminum chassis save roughly 2.5 pounds and offer vastly superior ergonomic adjustability for precision work. For pure hunting under 300 yards, the Stevens is the better value; for any task requiring repeatable sub-MOA accuracy from varied positions, the MPR's foundational rigidity and 1:10" twist rate for stabilizing heavier bullets make it the definitively better tool.
What does it weigh and what are the dimensions?
The rifle weighs 6.90 pounds (3.13 kg) without optics, with an overall length of 37.5 inches with the stock folded. The centerpiece is the 20-inch (508 mm) carbon-fiber-wrapped barrel with a 5/8-24 thread pattern, providing a 16.5-inch sight radius if using iron sights (not included). The chassis accommodates AICS-pattern magazines, and the free-floating carbon fiber handguard has M-LOK slots at the 3, 6, and 9 o'clock positions for accessory mounting.
Who is this NOT for?
This is not for the budget-conscious plinker or someone seeking a classic wood-stocked hunting rifle. If your primary use is firing fewer than 20 rounds per session from a bench at a static 100-yard range, a more affordable option like the Stevens 334 makes more financial sense. It's also not ideal for those wanting to shoot the cheapest surplus 7.62 NATO ammo exclusively; while it will function, achieving the guaranteed sub-MOA accuracy requires consistent, quality factory match or hand-loaded ammunition.
What's in the box?
You receive the complete Christensen Arms MPR rifle, one 5-round AICS-pattern metal magazine, the factory-installed stainless steel baffle muzzle brake, and a owner's manual detailing the Sub-MOA Guarantee. Christensen does not include a scope mount, bipod, or case. The trigger is a factory-installed TriggerTech unit, preset to a crisp 3.5-pound pull weight out of the box, which requires no immediate adjustment for most precision work.
Is the Christensen Arms MPR worth it at $2199.99?
At just under $2200, it's worth it for the shooter who will exploit its weight and accuracy advantages in competition or demanding field conditions. You are paying for the carbon fiber barrel technology which costs nearly $800 alone if purchased aftermarket, the fully adjustable folding chassis, and the guaranteed sub-MOA performance. If your needs are met by a $600 rifle, this is overkill. But if shaving 2.5 pounds from your pack and guaranteeing half-minute accuracy matters, this platform, like a dedicated competition shotgun such as the Stevens 555 Sporting, represents a focused investment in a tool that removes equipment as a limiting factor.

Frequently asked questions
- Is the barrel threaded for a suppressor?
- Yes. The barrel has a standard 5/8"-24 thread pattern under the factory muzzle brake, which is direct-thread compatible with most .30 caliber suppressors like those from SilencerCo or Dead Air. Removing the brake requires a 3/4" crowfoot wrench or a properly fitted armorer's tool to avoid damaging the Nitride finish.
- Does it come with a scope mount?
- No. The receiver has a flat-top Picatinny rail machined directly into the chassis, but you must provide and install your own scope rings or a cantilever mount. I recommend using a high-quality mount from Spuhr or American Rifle Company to maintain zero, especially with the folding stock mechanism.
- What magazines does it use?
- It uses standard AICS-pattern .308 Winchester detachable box magazines. The included magazine is a 5-round metal unit, but it reliably feeds from many aftermarket brands like Magpul's 10-round PMAG or Accurate Mag's offerings. Always function-test your specific magazines with your chosen ammunition.
- Is the folding stock NFA-compliant?
- As configured with the 20-inch barrel, yes—the overall length exceeds 26 inches. However, if you were to install a barrel shorter than 16 inches, the folded length might dip under 26 inches, potentially creating an NFA-regulated Short-Barreled Rifle (SBR). Always consult current ATF rulings and measure your specific configuration before modification.
- How long does shipping take to an FFL?
- For in-stock items, processing takes 1-2 business days, with ground shipping typically adding 3-7 business days depending on destination. All firearms must ship to a licensed dealer (FFL) of your choice, whose information we must verify before shipment. You will receive tracking once the carrier scans the package.
